Coal gasifier

Principle and technics of
coal gasify.

-The technics of coal gasify
: The coal is feed into an airtight vessel, under certain pressure and
temperature, the coal will occur reaction with air and water, then create CO,
H2 and other flammable gas.

-At first, coal is
transported to furnace top by elevator, then, coaling device feed furnace, the
coal treated with by several working procedure, for instance : dry,
carbonization, deoxidize, oxidation and so on, the residue will be discharge by
ash pan in bottom of furnace. At the same time, the air, which supplied by fans
in bottom of furnace, will mix withsteamwhich produced by furnace
wter jacket, the mixture will flow towards upper and through coal layer, the,
occur deoxidize reaction nd oxidation reaction with coal, in final, the
flammable gas is mad.

-After falling ash and
collecting dust, the flammable gas is transported to gas user, this is hot coal
gas technics.

-The coal gasifier completely
satisfy eith the requirement of environment protection, The Ringelman darkness
of tail gas can achieve 0.5 class, the soot let can be less than 80mg/Nm3,
achieve the environment protection standards in 1 class area, doesn’t need any
treatment equipments for tail gas.

-Be low price and low running
expense. Compare with burning oil and natural gas, the coal gas can save 70-80%
of total running expense and is equal with burning coal directly.

Based on the same quantity of heat ( 10000 Kcal ), the cost
of burning oil is Rp 3.800 – Rp.6.500,-, the cost of burning LPG is Rp 4.500,-,
the coat of coal gas just and it’s Rp 900,-, therefore, we can judge that coal
gas has large superiority and its environment protection effect is same as
burning oil and burning natural gas. So the running cost is saved hugely ,the
competitiveness of corporation is increased.

-Improving the working and
operation surrounding on site. The working surrounding of burning coal directly
is too bad, dirty and dusty. The heat quantity is difficult to control. If
using coal gasifier, the operation surrounding is clean and we can adjust the
heat quantity according as technics requirement at any time.

-Improving the produce
efficiency of equipment. Because has high heat transfer efficiency, under the
same condition, the efficiency and capacity can be improved 5 ˜ 10%. The sample
is : One chemical factory in Bogor, after changing to use coal gasifier, the
heating effieciency is improved to 70 % from 80%. Under using the same amount
of coal, the capacity is improved 30%. Just spend 3 monts ; the whole
investment is draw back and getting goog economy efficiency.

The coal will be the main energy sources for along time in
world. Coal gasifier is thebest to rebuild the coaling kill. Many successful
cases can prove that the coal gasifiercan drastically solve the problem of
environment protection of buring coal : also, theystill can improve the
production efficiency increasing benefit of corporation.
